SIMEN Precast, a Qingdao-based manufacturer of precast concrete accessories, offers spread anchors designed for safe lifting and transportation of precast concrete components across residential, commercial and infrastructure construction projects. The spread anchor is cast into precast panels during production, creating a secure embedded connection point for lifting equipment when elements need to be demoulded, moved and installed on site. Combined with matching plastic plugs, the product protects the anchor hole from concrete grout penetration during casting and simplifies cleaning after demoulding.

The spread anchor features a split, flared lower section that forms mechanical interlock within hardened concrete. This geometry distributes load over a larger concrete area compared with single-point anchors, reducing local stress concentration and lowering the risk of concrete spalling under working load. Two mounting holes on the upper body allow flexible connection with lifting shackles, adapting to different lifting configurations for wall panels, slabs and other modular precast units. The product is manufactured to consistent dimensional tolerances to maintain predictable performance in batch precast production.

Precast producers face recurring challenges in lifting heavy precast elements, including inconsistent embedment, hole blockage and premature concrete cracking. SIMEN Precast developed its spread anchor system to address these practical site and factory concerns. The paired plastic plug fits neatly into the anchor’s opening before pouring, preventing mortar from filling the connection cavity. Once concrete gains sufficient strength, the plug can be quickly removed, leaving a clean socket ready for lifting hardware without extra chipping or grinding work.

The anchor undergoes load testing to verify compliance with common precast industry design requirements. SIMEN Precast provides technical documentation including load capacity data and installation guidance to support precast engineers in anchor layout and structural calculation. The product range covers multiple sizes to match varying panel weights and thicknesses, supporting small precast workshops as well as large automated precast factories serving export markets in Europe, Australia and Southeast Asia.

As modular construction continues to expand globally, reliable embedded lifting hardware remains essential for precast project safety and efficiency. SIMEN Precast continues to collaborate with precast fabricators to refine accessory designs for real-world factory conditions. The spread anchor joins the company’s existing portfolio of lifting, transport and formwork accessories, supporting precast manufacturers to streamline production workflows and maintain stable handling performance throughout the component lifecycle.
